【swoole】PHP＋Swoole+Linux實現進程監控

 

腳本代碼

class Server
{
    const PORT = 8888;

    public function port()
    {
        //netstat -anp 2>/dev/null| grep 8888 |grep LISTEN |wc -l
        $shellCommand = 'netstat -anp 2>/dev/null| grep ' . self::PORT . "| grep LISTEN | wc -l";
        $result = shell_exec($shellCommand);
        if ($result != 1) {
            //進程不存在，發送警報信息
            echo 'At '.date('Y-m-d H:i:s') . ' service process is exit' . PHP_EOL;
        } else {
            echo 'At '.date('Y-m-d H:i:s') . ' service process is ok' . PHP_EOL;
        }
    }

}

Swoole\Timer::tick(1000, function (int $timer_id) {
    (new Server)->port();
});

 

nohup /usr/bin/php ./Server.php > ~/test.log &

更加精確的寫法
netstat -anp 2>/dev/null| grep 127.0.0.1:8866 | grep LISTEN | wc -l
